PBS to SLURM migration
CNES HPC cluster will move from using PBS to Slurm. This will need changes in iota2. From a look at the documentation, it seems that porting the code is rather easy since there is nearly a 1 to 1 mapping between both scheduling systems in terms of parameters and workflow.
We have requested an access to the Slurm test environment that will be available for several months before the actual migration happens.
I think that the use of PBS should not be removed from iota2 even after the migration in case some users need it and that we should only deprecate PBS if keeping it induces maintenance costs. This means adding an option to choose the HPC scheduler, whose default will be PBS until the migration and Slurm afterwards.
